I have a dataframe with column names, and I want to find the one that contains a certain string, but does not exactly match it. I’m searching for 'spike' in column names like 'spike-2', 'hey spike', 'spiked-in' (the 'spike' part is always continuous).
I want the column name to be returned as a string or a variable, so I access the column later with df['name'] or df[name] as normal. I’ve tried to find ways to do this, to no avail. Any tips?
